STEVAL-ICB008V1 Touch-sensing software library demonstration board based on the STM8S Data brief Features ■ Small outline with high density demonstration functions ■ Powered by USB port without extra specific equipment/cable ■ Two demonstration modes: offline and online ■ Direct configuration for demonstration board via PC software ■ Touchpad information logging on PC ■ SWIM port reserved for debug use ■ RoHS compliant STEVAL-ICB008V1 Description The STEVAL-ICB008V1 demonstration board is designed on the STM8S RC touch solution enabling users to better understand the functions and performance of STMicroelectronics capacitive touch-sensing. The complete demonstration kit consists of 3 parts: an evaluation board, a PC GUI program and a USB cable (standard-B to mini-B). Powered by the USB port of the PC, the board can be demonstrated in standalone. 19 LEDs are used to indicate touchpad information, including 11 keys and 1 slider. In addition, there are another 3 LEDs on the board indicating the system general status. With a PC GUI program, the STM8S RC touch solution provides a simple platform to monitor more detailed information as well as configure critical parameters of the touch-sensing process. For further details about the solution, please read the technical documentation available on www.st.com/touch-sense-sw-lib/.
